If you're one of the Covidiots who believe that COVID-19 is "just the flu",
that the 2020 election was stolen, or
especially if you supported the 1/6/21 insurrection,
leave now.

Two vs. four, but also the difference between pre-noise pollution/post and pure turbine (707) and turbofan (787). And the other piece is the advances in technology in 50 years!!!
Those four JT3D-3Bs had 18,000lbs of thrust apiece, while those two GEnx engines have about 57,000lbs of thrust apiece.
Cool.
I still loved #1.

Went to an air show a few months ago (before obummer killed them off) and saw F-16s, F-18s, and F-22s in action. I've always loved the noise and enjoyed the F-16 for that reason. The F-22 is an amazing bird, but you just can't beat the sky-ripping noise of the older engines.
